Android 如何使用fragment移动到同一选项卡中的其他布局

大家好，我正在通过扩展fragment activity创建tabview，它正在正确显示，但在我的第一个选项卡中，当我单击该视图时，我有一个listview，我需要移动到另一个视图，但在同一个选项卡中，我知道如何通过tabactivity创建tabview，但我不知道如何在tabview中正确使用fragment activity因此，如果有任何关于带有片段活动的tabview的教程链接将非常有用。这是密码

public class FragmeActivity extends FragmentActivity implements TabHost.OnTabChangeListener {

也许说你想看什么会更好？也许这里的人不太会使用你提出的技术片段？@gangnus我想在同一个选项卡中从一个活动转移到另一个活动
